HANDLE ARRANGEMENT FOR BRUSHES Filed May 27, 1949 INVENTOR. Art hur Lo. Barre.

ATTORNEY Patented May 27, 1952 UNITED STATES PATENT OFFICE This invention relates to a handle attachment for brushes, mops and similar cleaning devices having a backing member. 7

In the past, handle attachments of this nature have required that the backing member of the brush be of a particular shape, or that the backing member be provided with special indentations and/or apertures for mounting the attachment. Certain of the known prior art devices have been further complicated and made expensive by the use of machined parts and springs.

It is an object of the present invention to pro vide a simple, self-contained, rotatably adjustable handle attachment of the character described, which can be easily attached to the usual backing member of substantially any standard brush, pad or mop without materially altering said backing member.

It is a further object of the invention to pro vide simple, efiective, handle attaching means of the character described requiring no machined parts with the exception of standard bolts and screws.

These and other objects of the invention will be manifest from the following brief description and the accompanying drawings.

Of the accompanying drawings:

Figure 1 is a side view illustrating an attachment embodying the features of the invention, the same being shown secured to the backing member of a brush, and also showing in dotted lines the reversed position of the handle.

Figure 2 is a cross-section taken on the line 2-2 in Figure 1.

Figure 3 is a top plan view of the attachment, showing in dotted lines the position of the handle when partially rotated towards the reversed position.

Referring particularly to Figures 1 and 2 of the drawings there is illustrated a handle attachment, indicated generally at Ill, embodying the features of the invention, the same being shown secured to a backing member ll of a brush [2, for attaching thereto an elongated handle I3 to extend at a suitable inclination from the backing member.

The handle attachment Ill may include a base plate M of thin metal adapted to be secured to the backing member I l, by means of wood screws l5, l5, received through spaced apertures l5, [6 in the base plate. Plate M has formed therein intermediate the spaced apertures iii, a hollow protuberance I! which projects upwardly of the top face of the backing member to provide a recess for full reception of a head 18a of a bolt i8 re- 1 Claim. (Cl. 306--6) 2 I v ceived through an aperture in the protuberance and held in that position by securement of the plate to the backing member.

superposed on plate I l may be a handle mounting plate I9 having a hollow conical protuberance 20 which complementally engages over the protuberance I! having a square aperture therein for reception of a squared portion of a carriage bolt 28 therethrough (see Figure 2). Two relatively small indentations 28, 28 in plate l9 provide recesses for snug receptionof the heads of said securing screws l5 which, when the plates [4 and 19 are clamped together by turning wing nut 22 on the outwardly projecting end of threaded bolt I 8, prevent rotation of the plate i9 relatively of plate l4.

Integral with plate l9 and extending at approximately 45 to the plane thereof is a tubular extension 23 adapted to receive the end of the handle iii, the same being secured in place as by a screw 24.

The attachment is adapted to be sold or supplied as a self-contained unit including the base plate It and handle-mounting plate [9 clamped thereto by means of bolt l8 and nut 22, in which instance the two screws l5 may also be supplied with the unit with the heads I5a thereof engaged between said plates, as shown in Figure 2.

In use of the unit to attach the handle Hi to a scrub brush I2, for example, the wing nut 22 is loosened to permit turning handle plate [9 with respect to plate 14, as indicated in chain-dotted lines in Figure 3, to allow securing base plate M to the usual wood backing member ll of the brush by means of the screws I5. When this is done the plate i9 is turned until the small indented portions 28 are aligned with the screw heads 15a and then the wing nut 22 is turned to clamp the plates l4 and 19 together in the manner previously described. The attached unit is then ready for insertion of a handle in the tubular extension 23.

With continued use of the brush 12 with the handle I3 in one position the bristles of the brush will tend to wear down to one side of the brush. When this wear occurs the wing nut 22 may be loosened sufliciently to disengage the screw heads I50, from the indented portions 28, thereby to permit rotation of plate I9 through until the screw heads become engaged in corresponding indentations 28, and then the wing nut 22 is turned to clamp plate [9 non-rotatably to base plate M. In this manner, the brush is conditioned for additional wear.

Although the improved handle attaching device has been described in detail with reference to a scrubbing brush, it is clear that it may be similarly secured to backing members of many other cleaning, polishing, or treating brushes or pads.

It will be readily seen that the improved attachment is particularly adapted to be economically produced by means of metal stamping methods.

Thus, has been. provided an improved selfcontained handle attaching device for brushes or the like, which accomplishes the stated objects of the invention.

Modifications of the invention may-be resorted V to without departing from the spirit of the invention or the scope of the appended claim:

What is claimed is: A handle attachment for brushes or pads having a backing member, comprising a base plate;

having an upstanding .hollow conical protuberance providing a recess in the underside of the plate said protuberance having anaperture in the wall thereof at the upperendtof the same, a bolt received upwardly through the aperture of the protuberance .andhaving a head received in said recess to be above the underside of the base plate, said plate having holes therein at opposite sides of said protuberance, screws inserted downwardly through said holes for fastening the base plate to a said backing member and having heads thereof protruding upwardly of the base platera pressed portions providing recesses for snug reception ,"Of Zthe'heads :of the fastening screws when the base and mounting plates are clamped together, thereby preventing relative movement between said base and mounting plates, and socketmeansonsaid mounting plate for securing a handle thereto.
